HVDC Transmission Efficiency Simulation Enhancements

I have already built a two-terminal HVDC transmission model in MATLAB/Simulink that incorporates power-flow control and has demonstrated a 20 % overall efficiency gain in preliminary tests. My next objective is to push that figure higher by targeting energy-loss reduction while validating the model’s behaviour under grid-interconnection scenarios. Here is what I have in place: • A functioning Simulink schematic of the converter stations, DC line, and AC grids • Basic power-flow control logic that balances the two terminals • Data from the first round of simulations confirming the current gain Where I need your help is in refining the model so that every avoidable watt stays in the system. Specifically, I want to: • Identify and quantify dominant loss paths (converter switching, line resistance, filters, etc.) • Introduce or improve component-level tweaks—topology choices, modulation schemes, or control-loop tuning—that directly cut those losses • Verify stability and performance when the HVDC link is tied into a realistic AC grid on either end, including fault-free steady-state as well as fast transients • Document the changes clearly enough for me to trace every calculation Deliverables 1. Updated MATLAB/Simulink files with annotated blocks and parameter sets 2. A concise technical note (PDF or Word) summarising methods, assumptions, and before/after efficiency metrics 3. A short walkthrough video or live session (≤30 min) so I can reproduce your results Acceptance Criteria • Re-simulations prove a measurable efficiency improvement beyond the current 20 % baseline, with plots and numeric tables to back it up • The grid-interconnection test cases run without numerical instability or unintended power oscillations • All custom scripts compile and execute on MATLAB R2022b without additional toolboxes beyond Simscape Electrical If you have hands-on experience with HVDC control, PWM strategies, or loss modelling, your insight will be invaluable.
